Fiberglass
Windows have the lowest overall environmental impact. The energy efficiency
and long life of fiberglass windows significantly reduces the need for
purchased energy, which means that their impacts on resource depletion
and embodied energy is also limited. The high energy use and to a lesser
extent, the emission during production of aluminum-clad wood and vinyl
windows were the principle factors working against these products.

Over the years
we have learned that building methods and materials can affect the
health of occupants. Fiberglass Windows are selected by Canada's
CMHC (Central Mortgage and Housing Corporation) when specifying
windows for occupants that are highly susceptible to, or have chronic
allergic reactions to materials.

In North America
every local Gas Station was required by law to dig up their Steel
Storage Gas Tanks and replace them with Fiberglass, as the material
least likely to corrode, rot, disintegrate and leak its contents.
For the same reason the storage of toxin chemicals is stored in
a fiberglass container.

Fiberglass is
an inert material that is nonpolluting,
meets the needs of people concerned with their health and environment.
Fiberglass rovings and mats are made from pure silica sand, requiring
less energy to produce into a finished product than PVC or Aluminum.
Sand is more plentiful than our forests. Sand is an inert natural
occurring product, that does not contribute to environmental degradation
or deforestation.

Fiberglass Windows were selected as the material of choice by
"Health House" in Toronto Canada, a project to design
and promote the reduction of emissions of chemicals and vapor
that cause indoor pollution in home construction. Fiberglass was
selected as the most environmentally friendly materials under
criteria that vinyl and wood can meet.
